Nomaco Kflex 801-LRE-100318 3-1/8" 90° Elastomeric Elbow Pipe Fitting

Elastomeric Elbow for 3-1/8" Tube

This NBR/PVC elastomeric fitting insulates a 90 degree elbow on 3-1/8 inch outer-diameter pipe. The black insulation carries an approximate R value of 6.2 and withstands temperatures from -297 to 220 degrees F. It suits commercial piping, ductwork and tank installations that demand closed-cell thermal protection.

HVAC Installers and Maintenance Teams

Technicians insulating chilled-water, refrigerant or low-pressure steam lines will find the material flexible enough to wrap tight bends without splitting. It is not suited for exposed outdoor runs that require UV-resistant jacketing, nor for systems that operate above 220 degrees F. Buyers needing fire-rated wrap or thicker wall sections should seek alternative products.

R-Value 6.2 and 1-5/64" Wall

The 1-5/64 inch wall delivers R-6.2 performance, controlling condensation and heat gain on 3 inch nominal tube. It handles sub-zero chillers down to -297 degrees F and moderate heating up to 220 degrees F. Beyond that range the elastomer can degrade, and the fixed 90 degree geometry cannot accommodate custom angles or larger diameters.
